摘要
Techniques for implementing data deduplication in conjunction with thick and thin provisioning of storage objects are provided. In one embodiment, a system can receive a write request directed to a storage object stored by the system and can determine whether the storage object is a thin or thick object. If the storage object is a thin object, the system can calculate a usage value by adding a total amount of physical storage space used in the system to a total amount of storage space reserved for thick storage objects in the system and further subtracting a total amount of reserved storage space for the thick storage objects that are filled with unique data. The system can then reject the write request if the usage value is not less than the total storage capacity of the system.
